Why is Solaris always booting into the Device Configuration Assistant (DCA)?

This is usually caused by one of the following:

You installed Solaris onto a disk other than the primary boot disk.
You didn't remove your DCA boot diskette or
if you didn't remove your installation CD-ROM if it's in a bootable CD-ROM
drive.
File /boot/solaris/bootenv.rc is corrupt or truncated,
usually after a hard reboot or reset.
This file is setup and used by DCA.
It should contain several lines.

To change or set your default boot device,

for instructions.
To summarize:

From the "Boot Solaris" screen, press F4 (Boot Tasks).
On the "Boot Tasks" screen, press Enter to place an "X" in
front of "View/Edit Autoboot Settings."
In the "View/Edit Autoboot Settings" screen, note that the
Default Boot Device will not be set to any valid device.
Place an "X" in front of Set Default Boot Device and press
F2 (Continue).
On the Set Default Boot Device screen, place an X in front of the
correct disk and press F2 (Continue).
Arrow up to the Accept Settings and press Enter to mark with an "X".
Press F2 (Continue) to return to the Boot Tasks screen.
Press F3 (Back). It will load appropriate drivers after which you
will be at the Boot Solaris screen. Press F2 (Continue) to continue
booting.
